This is a duplicate of #12053. Thanks for filing it!

Someone above had OpenGL 1.4, which we won't be supporting - but this is probably a software issue on that user's machine, as even OpenGL 2.1 is ancient and should be supported everywhere

Unfortunately that's not the case, as the ubiquitous Intel 945GM graphics chipsets only support up to 1.4 due to a lack of occlusion support. For example we've just updated all our laptops to Ubuntu 16.04 and they're all resolutely stuck on OpenGL 1.4 for this reason, so Servo isn't an option for them.

In terms of Intel integrated graphics, OpenGL 2.1 is only available from the 965 chipset onwards.

Might be worth adding a few lines to the 'try Servo nightlies' page that older laptops should probably stick with Firefox.

@po4y Interesting! Do you know when those laptops were manufactured? Wikipedia page suggests that the 945GM chipset was released in 2006 - but perhaps they are still being shipped in some recent hardware?

An interesting option that I'd like to try out is running webrender on top of SwiftShader (see https://blog.chromium.org/2016/06/universal-rendering-with-swiftshader.html) and see what the performance is like for older / buggy hardware.

[po4y]

Youngest 945-based laptop I can find here is a 2009-ish Dell Latitude. After than Intel seemed to shift that chipset into the netbook-niche, until it was discontinued around 2011 or 2012. Not very easy to find definite info online though.

I'll try SwiftShader on a couple of the old machines here and report back. Thanks!

I don't think you'll be able to try SS without a lot of code changes - so it's not an immediate fix. But it's something I would like to try and get working in the near future.
